E. S. SCRIPTURE, OF NEW'V HAVEN, CONNECTICUT.

WINDOW-FAsTENER.

Specification of Letters Patent No. 19,588, dated March 9, 1858.

To aZZ whom 'it may concern:

Be it known that I, ELIPHALET S. SCRIP- TURE, of New Haven, in thecounty of New Haven and State of Connecticut, .have invented a new anduseful Improvement in Window Fasteners or Locks; and I do hereby declarethat the following is a full, clear, and eXact description of the same,reference being had to the annexed drawings, making a part of thisspecication, in which- Figure 1 is a side sectional view of myimprovement. Figs. 2, 3 and 4 are perspectives of the same. Fig. 5, is aperspective sketch of the model.

Therefore, I proceed to fully describe my invention. v

A represents the under half of a divided tube, or cylinder, providedwith -half circle heads a, a, at, orv near each end, provided each witha central semicircle aperture.

B represents a small metallic piece having upon it a small projection ornipple, rising up from near its center as at b, which I denominate avibrating tracer, the same being fitted for, and placed in, or near, thecenter and bottom of said lower half tube A in a recess provided for it.

C represents a piece of india rubber which I call a pillow block, and isplaced between the forward head a, and the tracer block B.

D represents a piece of wood placed between the back head a, and thetracer block B, and is called the regulating block.

E represents a shaft, or bolt, the back end, (as at little 0,)representing a square, to receive a key, or crank, the opposite, orforward end is provided with a flange, represented at CZ, and is largerin its diameter than the bolt E, said flange representing about aquarter circle, and formed into anl abrupt incline plane, or wedge;about a half inch back of this flange d, commences a spiral groove,shown at e, commencing very abrupt, and as it recedes back, and aroundthe bolt E it terminates at about two thirds of its circumference in adead plane, or rather returning again toward the forward end, this boltE, is placed in the half circles a a, at the same time resting upon andover the pillow block C, the regulating block D, and tracer'B, receivingin the groove e, the tracer nipple F y represents the upper half of thetube A which is provided with three half heads or partitions a a a,having in them corresponding semicircles to fit over bolt E, so Y thatwhen placed over, and secured to the lower half tube A, it serves toconne all parts snugly together f f f f representing wings, with guidepin and hole g g, which serve to secure the half tubes together, andkeep all from turning when in use.

G represents what I term a catch stud, which is to be properly, andfirmly attached to the outer sash XI, said catch being provided with ahole through it, the upper part presenting a downward projecting flangeL, which is in form-of a wedge, or abrupt plane, which corresponds withthe quarter circle flange d, upon bolt E; when all being thus arranged,with the tube attached to, or inserted in the inner sash X as is shownin Fig..1 by then applying the key, or crank upon the square c, of boltE, and turning to the right, the bolt E advances rapidly forward, untilits quarter circle flange d, takes firmly behind the flange z, upon studG, when the terminating' incline plane in the bolt groove e, commencesto drive the tracer B b, forward against the rubber pillow block C, andhauling back upon the catch stud and flange Gr 7L, thereby drawing, andholding together the two sashes under the elastic pressure of indiarubber pillow block C; which also serves, (by its yielding quality) -tocompensate for any lit-tlc imperfection of work, or variations in space;the regulating block D, serves to hold the tracer B l), to its place, aswell as to regulate its position in the recess of tube, -by diminishingor adding to its length, providing a cheap, and ready mode of regulatingthe pinch, or draft, upon the incline planes.

The advantages claimed for this rimprovement, are firstly its eXtremesimplicity, its small, compact and convenient form, its small cost, itsready adaptability, and strong, effective operation and security,drawing the window, both together, and downward, at the same time whenthe neck groove z', back of flange (Z, is made eccentric for thepurpose. Secondly its being tubular, allowing it to be inserted withinthe sash, renders it much less liable to injury from external causes,and much less in the way in cleaning the windows. Thirdly its partakingof the character of a lock, from which the key may be removed, providesfar more safety against roguish children, or criminal burglars. Fourthlyit is a sovereign remedy for rattling Windows.

Having thus fully described the nature of my invention, and set forthits advantages, I will say that I am aware that bolts with spiralgrooves formed in them, have been used before, for various purposes, Itherefore do not claim such; but,

What I do claim as new, and desire to se- Cure by Letters Patent, is-

The vibrating tracer B b, (or in other words, small section of a screwnut allowed to be vibratory in its operation) in combination with theelastic pillow block C, the regulating block D, the bolt E, and thecatch stud G, with their flanges and incline planes, all being securedin a two part tube,

'and all being arranged substantially in the manner, and for thepurposes set forth.
